Application filedliovember 3, 1913. Serial No. 798,836.

To all whom it may concern.

Be it known that I, IIALLETT D. ELLs, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Chocks for Vehicledlhcels, of which the following is a specification. 7

My invention relates to improvements in cho cks for vehicle wheels. 1

It is particularly adapted for use on an automobile wheel.

. The object of my invention is to provide a chock which is provided with means for being releasably locked to an automobile wheel for the purpose of preventing the wheel from revolving, and thereby reventing theft or unauthorized use of t elautomobile. p

In the accompanying drawings which illustrate my invention, Figure lis a side elevation of the preferred form of my invention shown attached to an automobile wheel, the latter being in dotted lines, "Fig;

2 is an enlarged side elevation of the/choc u shown in Fig.1. Fig. 3 is a-vertical sec tional view on the line ab'of Fig. ti-"Fig.1

4 is a vertical sectional'view on the liner-Q1 of Fig. 2. Fig. 5 is a modified form bf my invention provided with two clamping arms acted to opposite sides of the tread mem- 'Similar leference characters designate,

ery of the tire 2 of an ordinary automobile wheel 3. Hinged to. one side of the body 1 by means of a pintle -t'is a clamping mem-' her 5 which is adapted to embrace the rim 6 of the automobile wheel as shown in Fig. 1, and to have its free end releasably locked to the opposite side of the body 1 by means of a padlock 7, the hasp 8 of which is adapted to be inserted through two holes 9 and 10 provided respectively in laterally extending flanges 11 and 12 with which the members 5 and 1 are rovided. Extending downwardly. and re erably obliquely, from the underside of t e body 1 is a projection 13 which is adapted to strike the ground and serve as a chock to prevent the wheel 3 being revolved, or in case that suflicient power is "ceiving the hasp of 21 shown in Fig. 1. The ody 1' is provided operated to cause the wheel to revolve, the projection 13 will cause the wheel to be raised from the ground and thenpermitted to drop during each revolution.

When the owner or operator of the automobile desires to use the same, the padlock T is removed, after which the member 5 may be swung so as ,to permit the chock to be removed from the wheel.

The ends of the body. 1, as shown in the drawing, are preferably downwardly curved so as to prevent their cutting the tire 2.

In thefform of my invention shown in Fig. 5, two-arms 5' are respectivel pivoted to opposite sides of the body 1' by means of two parallel longitudinal pintles' 4'. The free ends of the arms 5' are provided respectively with holes therethrgug h for readlock, such as is with downwardly and obliquel'v extending projection 13, corresponding in action and mode of operation to the corresponding part in the other form of my invention."

.When the owner or operator of an automobile desires to leave the vehicle without guard he may apply to .one of the wheels 9.-

chock corresponding to the one shown in Fig.1 or that shown in Fig. 5, and releasably secure the same to the wheel b means of a suitable padlock, as hereinbe ore described. If any unauthorized person at- ,tempts to use the vehicle the chock will interfere with the revolving 0f the wheel and will either prevent therunning of the auto- -mobile, or by' the irregular mow ement of the wheel will prevent rapid running of the machine and will serve to effect the detection of the person who attempts the unauthorized use of the vehicle. f

Modifications of my invention, within the S00 e of the appended claims, may be made wit out departing from its s irit. I

Having thus described my invention, what.

I claim and desireto secure by Letters Pat eat is,

1. A chock provided with a bod ada ted to engage the tread of the tire o a w eel, said body, having a downwardly extending projection adapted to engage the ground for retarding revolving of the wheel, an arm pivoted to said body and adapted to be swung to a closed position in engagement withthe rim of the wheel, and releasable means for locking said arm in the closed free end of said arm to the opposite side position. v01f said body.

2. A chock having a body adapted to .lln testimony whereof I have signed-my clamp the tread of the tire of a, Wheel, said name to this specification in presence of two 5 body-having a, downwardly and obliquely subscribi-ngswitnesses.

extending projection for enga 'ing the ground, on ar n pivoted to one si e of said HALLETT ELLS' body and adapted to embrace the rim of Witnesses: the wheel for holding the'body clamped to E. B. HOUSE,-

10 the tire, and releasable means for locking the HiimN W. House.
